摘 要:对舰船舱段模型进行了海上水下爆炸试验,试验的目的是测试药包处于不同水下深度时,舱段模型龙骨处冲击载荷的差别。试验时,测量了自由场压力和壁压。根据试验结果,给出了自由场压力与壁压实测曲线。同时,采用正向超压时间计算公式,和实测自由场冲击波长超压时间以及自由场压力峰值与壁压峰值进行了对比。最后利用matlab软件对自由场压力和壁压进行了定性分析。试验结果对海上水下爆炸理论分析和今后的海上水下爆炸试验均有一定参考价值。A submersible cabin model was employed to undergo an underwater explosion test. The objective of this test was to measure the different shock loads at the keel of the cabin model with the charges in various water depths. When testing, free-field pressure and wall pressure were measured. A test curve of free-field pressure versus wall pressure was obtained from the actual measured data. Meanwhile, the free-field wave length and wall pressure peak value were calculated respectively by using the representative formula. The average of over-pressure period was then calculated. Besides, the free-field pressure and wall pressure were also analyzed comparatively by the Matlab software. The test results will be useful to the theoretic analysis of underwater explosion at sea and provide a reference for the further shock test of ships.
